IMPROVEMENT IN DEVICE FOR SAW-CARRIAGES.

The schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that we, LEVI BLACK and MILTON GAFFNEY; of Logan, in thecounty of Hocking, and State of Ohio, have invented a new and improvedCombined Gauge and Clamping-Device for Saw-Oarriages, for holding turnedwork, for squaring-and sizing the same; and we'do hereb declare that thefollowing is a full, clear, and exact description ofthe-construction andoperation of the same, reference being had to the accompanying drawings,making a part of this specification, in which- Figure 1 is a plan fiew.

Figure 2-is a side elevation.

Figure 3, a perspective view of block, with notch for holdingworkcornerwise, for taking off the corners.

Figure 4, View of vertical singleplatc stop or holder detached.

' Like letters in different figures of the drawings indi cate likeparts.

, Nat-awe.

Our invention consists of adjustable holders, with clamp and gauge, forsquaring and sizing the unturned part of bed-posts, table-legs, andother turned Work, the holders at one end being two sliding plates,provided with flanges flaring in opposite directions. At

the other end of the saw-carriage, the holder is made v-shape, andattached to a sliding stop, with handle, which serves as a clamp.

A proper scale for gauging the size of the Work is marked on the slidingplates and on the saw-carriage.

A block with a v-shape notch is used for holding the work in properposition for taking off the corners, so as to form an octagon.

Construction.

A is the saw-carriage, on one end of which is attached the stationaryblock B. Slotted plates, a and b, provided with flanges at one end, areattached to block G is a block with a v-shape notch, to be used forholding the work corncrwise when the corners are to be taken off.

H is a single vertical plate-stop or holder, to be at tached to stop orclamp E, instead of holder F, when the work may require it.

The saw is hung so that the face thereof is at right angles with theface of the saw-carriage.

Operation.

The plates and holders being so adjusted as to'briug the work in therequired position to the saw, the carriage is moved forward. (See fig.1.) The side of the work thus straightened by the saw, is then turneddown upon the carriage, and the saw, working at right angles with theface of the carriage, squares the second side with the first, and theother two sides are squared in like manner, and the work made therequired size by means of the gauge on plate a and on carriage A.

If the work has one true side, that should be placed on the carriage andthe others squared to it, as above described.

To take off the corners and form an octagon, the notched block G isused. Stop or holder H is for use instead of holder F, when the work mayrequire it;

and any other centre or holder required may be attached to the slidingtop or clamp E, in same manner.

We are aware of the patent, No. 76,740, to O. P. .ifiurrna-n, datedApril 1868, for improvement in planing-machines, and we hereby disclaimthe use of the devices of that invention.

Claim.

Having thus fully described our illYCIltiOIl,

What we claim therein as new, and desire to secure by Letters Patent,is-

Adjustable plates (1' and I), holders 1 and H, sliding stop or clamp E,and plate D, herein described, constructed, combined, and arranged tooperate in the manner andi'or the purpose set forth.
